Subject: [PATCH] mac80211: don't look up stations for multicast addresses
Since multicast addresses don't exist as stations, don't attempt
to look them up in the hashtable on TX.

Subject: [PATCH] mac80211: remove drop_unencrypted code
This mechanism was historic, and only ever used by IBSS, which
also doesn't need to have it as it properly manages station's
802.1X PAE state (or, with WEP, always has a key.)
Remove the mechanism to clean up the code.

Subject: [PATCH] mac80211: don't look up destination station twice
There's no need to look up the destination station twice while
building the 802.11 header for a given frame if the frame will
actually be transmitted to the station we initially looked up.
This happens for 4-addr VLAN interfaces and TDLS connections, which
both directly send the frame to the station they looked up, though
in the case of TDLS some station conditions need to be checked.
To avoid that, add a variable indicating that we've looked up the
station that the frame is going to be transmitted to, and avoid the
lookup/flag checking if it already has been done.
In the TDLS case, also move the authorized/wme_sta flag assignment
to the correct place, i.e. only when that station is really used.
Before this change, the new lookup should always have succeeded so
that the potentially erroneous data would be overwritten.

Subject: [PATCH] mac80211: drop 4-addr VLAN frames earlier if not
connected
If there's no station on the 4-addr VLAN interface, then frames
cannot be transmitted. Drop such frames earlier, before setting
up all the information for them.
We should keep the old check though since that code might be used
for other internally-generated frames.

In ieee80211_build_hdr(), the station is looked up to build the
header correctly (QoS field) and to check for authorization. For
mesh, authorization isn't checked here, and QoS capability is
mandatory, so the station lookup can be avoided.

Subject: [PATCH] mac80211: avoid duplicate TX path station lookup
Instead of looking up the destination station twice in the TX path
(first to build the header, and then for control processing), save
it when building the header and use it later in the TX path.
To avoid having to look up the station in the many callers, allow
those to pass %NULL which keeps the existing lookup.
